+## Common Problems
+
+You may encounter these common problems that you would need to manage.
+
+### 1. Missing Imports
+
+In standalone structure, components must declare all their dependencies in `imports`. Forgetting this often causes template errors.
+
+### 2. Mixed Structures
+
+Combining modules and standalone in the same feature leads to confusion. Migrate features fully or keep them module-based.
+
+### 3. Routing Errors
+
+Incorrect migration from `forLazy()` to `createRoutes()` or `loadComponent` can break navigation. Double-check route configs.
+
+### 4. Service Injection
+
+Services provided in old modules may be missing. Add them in the component’s `providers` or `app.config.ts`.
+
+### 5. Shared Module Habit
+
+Reintroducing a shared module reduces the benefits of standalone. Import dependencies directly where needed.

 ## Conclusion
 
 Angular’s standalone component architecture is a significant improvement for scalability, simplicity, and performance. With latest version of ABP Studio, you can adopt this modern approach with ease—without losing support for existing module-based projects.
